the root areas only
yes, you can water them anytime. your watering the dirt around the trees, your not spraying the whole tree
with water. you can use a hoe and make a little berm around the trees, then you can fill it with water. you don't need to water again until the soil starts to dry out. you can put the trees on a drip line system with a timer. it's not expensive and you won't need to worry about it. i water my trees once a day for a half hour
with 2 gallon per hour emmiters.
Yes she can, but it would be better to water them in the early morning.
Well i'm asking this for my grandma. She wants to know if we can water our apple, pear, plum, and peach trees while it is sunny and hot. (they are in full sun) they are also pretty young so yeah, can we?
